I was wondering if there are instances where the fascist were banished, without having to rely on foreign army? For example, hijacking the fascist party with leftist sympathizers, or indirectly threatening the stability of the government by using fascist-handbook reactionary provocations? Or something like using economic arms to crush fascism?
Generally without revolution and agency for the population you mostly get change for the worse. See also how the Soviet Union deteriorated from it’s mission into a historical hellhole under Stalin
